The admins will then wait for the DNS records to expire before shutting the server itself down. By overriding the TTL you'll be sending traffic to a server that could be shut down. | |

Here is an ugly way: you could filter the incoming DNS answer packet with iptables, send it to a userspace program (NFQUEUE target) which will then counterfeit it to change the TTL.
